Once you go brass, you never go back.
You might consider changing your add to a WANT add.
Good luck. I have a gear that I'd sent to you for free, but it has cracks.... it won't last long. I had epoxy'd it on the surface to hold it together, but I ended up with a brass gear before I installed it. The electric windows SUCK in my humble opinion. I'd rather have ambi doors personally.
If you give me your address, I'll just send it to you. I don't need it and it may get you a little further. I just found it in my shed. It turns out I had epoxy'd a different one ( a more broken one). This one is cracked, but not that bad and certainly would be "dipped" in epoxy and it may work just fine if you're REALLL nice to the window when you make it go up and down...
Have to agree, great video. Helped me size up the task to fix mine. Failed on one attempt to buy repro gear but gonna try another source tonight when I wont get in trouble for playing on my computer at work!
